Patented July 3, 1934 PATENT OFFICE BOX Andrew Mathis Kamper, Surbiton, England, as-

signor to No-Nail Cases Proprietary Limited, London, England, a company of Victoria, Australia Application April 25, 1933, Serial No. 667,901 In Great Britain May 14, 1932 3 Claims.

Boxes are well known, of the folding blank type in which the bottom and two side members, and perhaps also the lid member, are connected and hinged together by flanged strips of metal, so

{5 that the two side members can be folded up into the upright position, and the end members, to complete the box, can be slid into grooves left between the ends of the hinged box parts and the flanges of the metal strips.

In boxes of this type, in order to keep the sides in the upright position and prevent them being pushed apart when the box is being packed and before the lid is shut down, it is necessary either to have the box inserted in a suitable frame or clamping device, or else means must be provided whereby, when the end members are inserted, they themselves hold the side members in the upright position.

According to the present invention, the en members of the box are provided with lugs standing at right angles to the plane of the end members, and these lugs are so placed that when the end members are slid into position, the lugs engage with the side members and between the outer walls of the side members and the inner side of the metal strip, so that in fact at either side of the end members the lugs engage outside the side members and prevent them from being pushed outwards. The said lugs are preferably flush with the vertical edges of the end members.

The invention is illustrated in the accompanying drawing.

Figs. 1 and 2 are perspective views of an end piece of a box fitted according to the present invention, respectively about to be engaged, and in engagement with one of the bound members of the box.

Fig. 3 is a perspective view of part of an end member fitted with an alternative construction ll) according to the present invention.

Fig. 4 is a perspective view of an end part provided with a further modified form of device.

Fig. 5 is a plan view of the device illustrated in Fig. 4, before bending.

Fig. 6 is a perspective view of part of the end of a box fitted with a further alternative arrangement according to the present invention, and

Fig. '7 illustrates on a smaller scale an end part fitted with this device, being inserted into position in a box of the type specified.

In Fig. l a is the end piece and b is one of the bound and hinged sides of the box. On the end part a is mounted the bracket 0 with a lug 0' extending inwardly, at right angles to the plane of the box part a. The side b of the box is bound and hinged to the bottom and opposite side of the box by means of the flanged binding strip at, fixed by means of teeth e in known manner. It will be seen that when the end part a is lowered into the position illustrated in Fig. 2 the lug 0' will engage Q between the outer side of the box part b and the inner side of the binding strip d. A similar bracket 0 on the opposite side of the end part a co-operates in like manner with a side of the box,

so that the opposite sides I) cannot be pushed 5? apart when the end part a is in position.

In Fig. 3 the end part a carries a. channel shaped fixture 1 having a lug f standing up at right angles to the part a and this lug co-operates with the sides of the box in the manner explained with regard to Fig. 1.

In Figs. 4 and 5 are illustrated a further alternative arrangement wherein a corrugated strip g having a lug g is driven into the end piece a of the box. The end g of the device is 117, bent at an angle to the remainder in order that it may occupy the correct position, as shown in Fig. 4, to engage with the sides of the box. It is desirable to fix the device g obliquely into the end part of the box in order to avoid splitting the 50 wood.

The preferred embodiment of the invention is illustrated in Fig. 6 where there is attached to the end part a of the box brackets it having lugs h. The lugs h are preferably tapered at their 8 lower end in order to facilitate insertion in the space between the sides b of the box and the binding strip (1 and to prevent the lugs from stripping splinters from the sides b of the box.

I claim:

1. In combination with a box having sides formed from a foldable blank and insertable ends, flanged metal strips marginally connected to the sides of the box, said sides being spaced from the flanges of the strips to provide grooves .5 which, when the box is assembled, receive the insertable ends, and said ends having means extending inwardly of the box to fit between the inner sides of the strips and the outer adjacent wall of the sides for maintaining the sides in their 219 assembled position.

2. In combination with a box having sides formed from a foldable blank and insertable ends, flanged metal strips marginally connected to the sides of the box, said sides being spaced 1 from the flanges of the strips to provide grooves which, when the box is assembled, receive the insertable ends, and means connected to the extremities of said ends and having lugs extending inwardly substantially at right angles to the ti ends, said lugs arranged to fit between the inner sides of the strips and the outer adjacent walls of the sides to maintain the parts in their assembled positions.

3. In combination with a box having, sides formed from a foldable blank and insertable ends, flanged metal strips marginally connected to the sides of the box, said sides being spacedfrom the flanges of the strips to provide grooves do i
